Togalk,
With respect, you're wrong about the visa suspension. In fact a person's residency / work visa is protected until the action is over. I (and some other colleagues) have recently filed an action against our employer (in DXB), as a result of which the company tried to suspend or revoke our visas. They were told in writing (as we were), by the court, that the law requires that the visas remain in place and valid until the action is finished -- even though some of the people involved were terminated. I have been coming and going for the past 4 months with a valid residency visa, even though I have quit the company.
Having said that, I would endorse the comments of others re having very little faith in any aspect of government in the UAE.
One piece of advice I would give to anyone contemplating legal action: Use an Emirati law firm and Emirati lawyers. If you use an expat firm, or expat lawyer, you will be seen to be waving a colonial flag at the court system.
My two dirhams worth,
Grizz
