Goldman Sachs’ junior bankers — known to log grueling 100-hour work weeks — are looking at a more than 20 percent raise next year, two people familiar with the bank’s plans told The Post. That raises the base salary for some first-year analysts to about $85,000 before they even collect their bonuses, one source said. Second- and third-year analysts would likely be making significantly more, depending on where they work within the bank and how much that division makes, the source said. There are no plans to change how much they could make in bonuses, according to the person. Leslie Shribman, a Goldman spokeswoman, declined to comment. The prospective raise, which hasn’t been announced by the bank, comes after Goldman in October granted its analysts Saturdays off.
