I have been working for the same employer in Thailand for over 10 years. Always had a work permit from that employer which is obtained from the onestop service (company is not BOI promoted). I would now like to add an additional employer (wife's company) to the work permit but have been told that I can not do this unless the new employer is an affiliated company of the first employer where affiliated means same shareholders or directors or similar connection. The new employer will meet the normal requirements of paid up capital and number of employees.

Can anyone here with two employers tell me if they found this rule or were they able to have two employers that were not affiliated.

Thanks for any advice you can offer.

You are allowed two different employers in a work eprmit, but the first employer must agree to the fact that yu will also have a second employer.

However, you mention the One Stop Service Center and they tend to have slightly different rules, so it might not be possible under their rules. (perhaps because the additional company doesn't fall under the One Stop Service Center).

It might mean changing to the normal labour office (and nromal immigration office, instead of using the One Stop in the future.

Thanks Mario, seems to me that you may be right about the One Stop Service being the root of my problem.
