Narrative:
Shuttle departed lga, whitestone climb, lga approach control advised turn left 040 degrees climb to 12000'. Shortly thereafter lga approach control advised radar indicated we were above our assigned altitude of 8000'. Traffic 10 O'clock, 3 mi, at 9000'. We advised traffic in sight and returned to 8000'. Traffic passed and we continued on course west/O further incident. Neither the first officer nor myself heard nor acknowledged a clearance to 8000', 12000' last received. Either short stop clearance was not given by ATC or clearance was blocked by striking company pilots or other sympathy pilots. Since 3/thur/89 company radio xmissions are continually blocked all frequency on a daily basis, possibly by strikers with trans-receivers in airport terminals in lga, bos and dca.
