Ron认为现在完成时和现在进行时都ok,但是尊重原句。尊重原句啊!!
the past perfect makes perfect (heh) sense here. the idea is that, lately, the women have been receiving support from labor.
the present participial form "are receiving" would also make sense, but remember that you aren't supposed to change the meaning of the sentence without a good reason for doing so.
