Be warned about a company which goes by the name of Yuming Education in Tianjin. Most of their ads have the header "High Salary Teaching Job In China". In these forums they are going by the username of "eduinter".
Yuming is a notorious recruiter who have conned many teachers over the years myself included. If you have a read through their ads and also their website you will see reference to the holiday periods. These are basically stated as being approximately 4 and 6 weeks and it goes on to state that during these "unpaid" holidays you have the option of taking leave or continuing at your full pay in one of Yumings teaching camps. This is not true. Yuming do not have teaching camps or any schools of their own in any way. They are a placement service, you work for a customer of theirs that being for the most part private schools.
The actual length of time you will be on holiday will be around 3 months in the Summer and 2 months in the Winter so all together 5 months. Plus you have all the Chinese national holidays to add on and any additional days where the school may be taking the kids on a field trip or when they are taking exams. All in all you are looking at around 6 months of the year on holiday and unpaid. They have little or no work to offer anyone during this period and given the fact that your contract will also have a clause in it which states that employees of Yuming cannot undertake any private work outside of Yuming when under contract the only way you are going to make ends meet is by breaking the rules of your contract.
Yuming know they don't have enough work to offer but fail to make this clear. When I worked there I specifically asked about additional work and was told not to worry. When the holidays arrived they had nothing at all.
Many teachers who have had no choice to do extra work to pay their rent and buy food have been found out and Yuming think nothing of informing the PSB and the police that you have been fired. The only person(s) they don't tell are the teachers leaving them on an illegal overstay, fined and kicked out of China. Those who complain they can't get by will be frowned upon and similarly disposed of as they fabricate some story of your failures as an employee and have even begun to build up a reputation with the PSB for this kind of thing in the city.
Those who attempt to leave Yuming with the intention of moving on to a new employer will find themselves in the position of being unable to do so as Yuming will not obtain the required documents from the PSB which are required to do a visa transfer. Your only hope then is to start the whole visa process from the beginning in your country of origin and if you hadn't planned a trip home is going to be very expensive and in many cases people just don't bother coming back.
There are complaints all over the internet about these people and all they can do is make empty threats of legal action which to date have never been followed through. They know they have cheated many people and do not have a leg to stand on but still post threats in some vein attempt to silence everyone. If they thought for a second they had a case they would not be wasting their time posting threats it would be in the hands of a solicitor.
Please please please take heed and avoid ruining your chosen life in China for the sake of some greedy little business that treat ESL teachers like dirt. There are so many decent employers around if you look, this place is just not worth the trouble.
