Not really. It's kind of what eroded the power of US industrial unions. In the 1970s many companies started hiring (with the grudging acceptance of the unions if their existing members got to keep their benefits) new workers with less benefits and less job security than previous workers. Within a generation the expectations for health plans, retirement, and paid vacations were reduced and the new workers if anything resented the older workers rather than their employers.
